head gates for irrigatiiig purposes, ci'ilv-r'sj,

sewers or the like in which a temporary supiort for the cement is required` and has for its object to provide a convenient and coperative arrangement of lieihle and adjust.-

ahle. mold members that. are more especially adapted for making head gates for irrigatin,r

urposes and capable of being easily applied Por use and in which the several mold niembers are all so. designed 'thi-.t they can he iiickly colla; .ed to he readily reuu'n'ed after t 1e cement li. been set or dried.

M3' invention consists in the novel coperative arrangement and detailed const-ruction ol' parts that will he first described in detail, then he specifically pointed out in the appended claims, reference lwing had to the ac-con'ipanying.r drawings, in which:

Figure 1. is a vertical. longitudinal section of in v arrangement of molds and shows them combined for receiving: the concrete illing. Fig. 2, is a cross section of the same on the line 2-2 of Fig. 1.` Fig. 3, is a similar view of the saine on the line. 3--3 of Fig. i. Fig. 4, is a horizontal section on the line t-4 of Fig. 1. Fig. 5, is a perspective view of the.

main orT jointjacket, the same being shown partly open and the top and end caps thereof as removed therefrom. Fig. 6, is a perspective View of the main pipe formingr the eollapsihle mold. Fig. 7, is a detail view of the supplemental or extension mold for the T joint jacket hereinaftervspeeilically referred to. Fig. S, is a diagrammatic section showing the complete cement head gate with the head gate filling: and pipe sections iii position. ln the practical application of my invention the same embodies three core or mold sections, the main mold section l Mv invention relates to the construction of,

forms the. T joint jacket, an extended colj .lapsihle tubular mold l around which the cej nient is set to form the pipe or main. and the f i at l0" and having vertical Asemi-circular extions andrhaving a reduced pendent portion extension mold 3 forme( of adjustable sccfor cxteniiiiw and o renin;y into the tubular c pipe. 'n forming mold 2.

The pipe forminzgr inold consists of a plu-- rality of segmental sections 20-20 prefer-l ably three, as shown. of sheet metal. These sections are held with their longitudinal' edges' overlappingr and two of said sections have their overlapping sections provided with elongated semi-circular openings 2 t-2t to provide an opening .r to receive the reduced end of the pendent extension of the mold niemher 3, iresently again referred to. At one end (or lhoth ends, il desired) the mold sections 20-20 have transversely elongated slots 2-22, the slots in the several sect-ions being in alineinent to receive the clamps screws 22M-#22 that earrv clamp mits 22S-23. the purpose of the slots, the

screws and the nuts lit-ing to provide. for the desired transverse adjustments et the. mold memlwrs Z2-22, .it being understood that after the cement is set or dried around the inold 2, the sections 20 can be readily eollapsed and withdrawn from the cement forming pipe.

The niold 3 is formed of four segmental overlapping sect-ions 30'* formed at. the upper end with transversely extended elongated slots 30-30 through which pass set screws 3l that carry clamp nuts 32 as shown. The lower ends of the sections 3() terminate ywith inwardly extended horizontal flanges 3?x and pendent supplemental segmental seetions 33 that form the tubular extension for entering the. opening Jainl the mold. 2, as clearl shown in Fig. 1, h v refcience'to which it will he also observed that the pendent por tion provides for an annular shoulder on the cement T that forms an opening I of a smaller diameter than the colla sihle core oi' mold 3 so that the pipe of smal er diameter than the vertical chamber of the head gat-e can be slipped down into the opening' .r for cn erating with the head gate valve as wil be presently more {ull}v explained.

It should be stated that in the practical operation of mv invention the mol( s are intended for working with wet mixed cement.

'The iiiaiii orT mold constitutes a jacket for holdingg` the cement around the molds 2 and 3 and is formed of two semi-circular sections lO-lo hinged at the lower end as for sliding thereon two end caps 6 6, Yeach having a central aperture 60 for that purpose.

The jacket mold sections are closed and held to such position by slipping the caps G- over the ends of the closed sections, the said caps having annular grooves 61 to receive the ends of the jacket mold, as clearly shown in Fig. l. or T-mold are extended to their maximum diameter desired and held to such adjustment by the. screws at the ends thereof'. 'After the jacket l and moid 2 have been set f as described, another cap member G2 is'v placed on the top of the vertically extended portion of the jacket mold 1 after which the mold 3 is slipped into the opening 6'.n in the i cap 62 Vand its pendentextension is pushed down'` into the o ening a; in the said mold 2. The sections of t e mold 3 are then adjusted and set.. The cement filliii7 is then poured into'the jacket to surround t e molds 2 and 3, the filling packing close under the bottom flange ofthe mold 3 so as to provide an opiening I to the horizontal pipe of a diameter smaller than the mold 3 so as to readily permit of putting in a smaller pipe 4, after the cement head gate has been completed.

After the head gate has been ici-mcd by thev setting of the cement, the mold 3 is collapsed i and drawn up from *to mold 2 which in turn is collapsed and is drawn out from the jacket 1, after whcch the several heads of the jacket are removed and the said jacket is spread f and also removed. After the parts have been removed as stat-ed, the pi ie 4 is lit into theopening :r and its upper eni is secured, in any Well known manner, to the closure plate 7 which is now supported unon the top ofthe frate and which carries a valve S of anv well i own tvpe and as is generally illustrated in 8 of the drawings. 'lo brace the pipe 4 a supplemental fillin;r oi cement, see lig. S, mijfbe used. e

om.' the foregoing, taken inconnection f, with-the accompanying drawing, it is lie-f lieved that the complete construction and manner vof operation of my invent-ion will be readily understood by those. skilled in the :ii-t to which it appertains.

Having thus described my invention, what I claim is: 'i

A l 3. A means for making cement head gates that comprises Y the. following elements in combination; a T shaped jacket formed of l separable members, apertured closure ineinl bers for the end of the jacket, a contractiiilc main core that extends lengthwise of the jacket with its ends projected through the end closures for the jacket and another coni tractible core, that projects through the other closure member for the jacket and rests upon i the main core.
